Ecological Evaluation of Sustainable Development in the Studied Farms of Przysucha County

The subject of the research involved the agricultural farms from the Przysucha county (Masovian Voivodeship, Poland). The assessment of ecological results from farms was the purpose of the thesis. Evaluation was made by using selected indicators: minerals balance, soil's organic substances balance and vegetation cover of soil's index. The research was carried out among 100 chosen agricultural farms, situated on light soil, i.e. rye soil. The ecological assessment of the examined farms showed that all of minerals balances (N, P, K) and soil's organic substances balances were positive. In the case of nitrogen, balances exceeded the limit value 30 kg N·ha^-1. Vegetation cover of soil's index, as regards arable land, did not reach the recommended value, i.e. at least 60%. However, the cover of utilised agricultural area soil was similar to the recommended level (>70%). That was because of the large orchards and permanent crops share in horticultural farms, as well as large permanent grassland share in bovine and mixed farms.
